to use the Concepts Guide Deciding whether to use the Concepts Guide This guide describes the concepts that inform ONTAP data management software, including cluster storage, high-availability, virtualization, data protection, storage efficiency, and security. You should use this guide if you want to understand the full range of ONTAP features and benefits before you configure your storage solution. If you want to create a basic storage configuration using best practices, you should choose the appropriate document from NetApp's library of express guides and power guides: • Express guides describe how to complete key tasks quickly using ONTAP System Manager. • Power guides describe how to complete advanced tasks quickly using the CLI. If you need reference and configuration information about the ONTAP capabilities described in this guide, you should choose among the following documentation: • High availability (HA) configuration High Availability • Cluster and SVM administration System administration • Network and LIF management Network management • Disks and aggregates Disk and aggregate management • FlexVol volumes, FlexClone technology, and storage efficiency features Logical storage management • SAN host provisioning SAN administration • NAS file access ◦ NFS management ◦ SMB/CIFS management • Disaster recovery and archiving Data protection ONTAP Concepts 5 ONTAP platforms ONTAP platforms ONTAP data management software offers unified storage for applications that read and write data over block- or file-access protocols, in storage configurations that range from high-speed flash, to lower-priced spinning media, to cloud-based object storage. ONTAP implementations run on NetApp-engineered FAS or AFF appliances, on commodity hardware (ONTAP Select), and in private, public, or hybrid clouds (NetApp Private Storage or Cloud Volumes ONTAP). Specialized implementations offer best-in-class converged infrastructure (FlexPod Datacenter) and access to third-party storage arrays (FlexArray Virtualization). Together these implementations form the basic framework of the NetApp data fabric, with a common software-defined approach to data management and fast, efficient replication across platforms. About FlexPod Datacenter and FlexArray Virtualization Although not represented in the illustration of the NetApp data fabric, FlexPod Datacenter and FlexArray Virtualization are key ONTAP implementations: • FlexPod integrates best-in-class storage, networking, and compute components in a flexible architecture for enterprise workloads. Its converged infrastructure speeds the deployment of business-critical applications and cloud-based data center infrastructures. • FlexArray is a front end for third-party and NetApp E-Series storage arrays, offering a uniform set

  • Using Red Hat Client with Netapp Storage Over NFS Bikash Roy Choudhury, Netapp October 2013 | TR-3183
    Technical Report Using Red Hat Client with NetApp Storage over NFS Bikash Roy Choudhury, NetApp October 2013 | TR-3183 Abstract This report helps you to get the best from your Linux® NFS clients when used in an environment that includes NetApp® storage. Most of the discussion revolves around Red Hat Enterprise (RHEL) clients. This document does not include best practices and recommendations for block protocols like FCP and iSCSI. The paper highlight some of the best practices and tuning parameters that would be required for running user home directories and regular UNIX® file systems. The paper describes various tuning options on RHEL clients and diagnoses performance and reliability problems. Every workload has a different access pattern and characterization; we recommend appropriate tuning on RHEL clients based on the workload characterization, which should not be treated as “one size fits all" for all workloads. Separate technical reports have been published for different applications that provide recommendations for specific workloads. In this paper you will learn where to look for more information when faced with problems that are d ifficult to diagnose. Storage tuning information specific to your application may be available in other NetApp technical reports and solution guides.
